AI Technical Summary

Technical Problem

Existing granule filling devices experience variations in the weight of granules filled in cartridges due to uneven layer thickness and insertion depth of cylinders, leading to inconsistent cartridge quality.

Method used

A granule filling device with a hopper and transfer unit that includes a leveling guide covering the granule layer from the upstream to downstream of the insertion region, guiding granules to form a uniform layer and stabilize the insertion depth of cylinders, using a block and plate structure to manage centrifugal forces.

Benefits of technology

The device achieves a significant reduction in weight variation, stabilizing cartridge quality by reducing the product rejection rate to a quarter of conventional levels, with improved uniformity and consistency in granule distribution.

Abstract

A granule feeding device (1) comprises: a hopper (2) in which granules that are a flavoring source are stored; and a transfer unit (4) that transfers the granules from the hopper (2) to a container (6) that constitutes a cartridge. The hopper (2) forms a granule layer (20) by fluidizing the granules. The transfer unit (4) has a cylinder array in which a plurality of cylinders (16) for capturing granules from the granule layer (20) are arrayed. The granule layer (20) has formed therein an insertion area (50) into which the cylinder array is inserted. The hopper (2) has a leveling guide (36) that, while exposing the insertion area (50), covers the surface of the granule layer (20) in a range spanning from the upstream side to the downstream side of the insertion area (50) in the direction of granule flow.
